Plants injured, 1879-80 — I do not think that any plant or tree 

 has been killed. Ivy growing upon some of the tall trees has lost 

 some of the leaves, but is growing again. A Magnolia about 25 ft. 

 high growing against the house facing S. E. has suffered the loss of 

 leaves and looks sickly. Of Roses, Gloire de Dijon, Marechal Niel 

 and others upon the house have not suffered. Laurustinus, all much 

 injured, some so much that they were cut down, but these have all 

 shot up again from the bottom, whilst those that were left are mostly 

 recovering. At Rothampstead, only one mile distant, but 20 ft. 

 higher, the Laurustinus scarcely suffered at all.
